Filter by:This trial studies how well dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) works in diagnosing osteoradionecrosis in patients with head and neck cancer that is primary, has come back, or has spread to other places in the body who are undergoing radiation therapy. DCE-MRI may help doctors to predict osteoradionecrosis in patient with head and neck cancer undergoing radiation therapy.
The investigators aim to develop a prospective database in which patient demographics, surgical, dental, prosthetic and QOL parameters collected during consecutive visits within the framework of routine practice, are being registered for each oncological patient eligible for (immediate/delayed) fixed prosthodontic rehabilitation at time of oral cavity reconstruction
Mandibular osteoradionecrosis, despite its low incidence, remains being the most problematic and irreversible complication after head and neck radiotherapy with no medical treatment to limit or reduce symptoms. Different clinical trials have shown a significant scientific evidence that the treatment with pentoxifylline + tocopherol achieves a certain effectiveness in the treatment of the tissue fibrosis. This study proposes to use this drugs to determine if there is healing of mandibular osteoradionecrosis and/or a symptomatic improvement as well.
The purpose of this study is to measure the two-year rate of tooth loss in patients who have received external beam radiation therapy with curative intent for head and neck cancer. The study will also evaluate the sequelae of radiation therapy and oral complications that may occur as a result to receiving radiation therapy.
The purpose of this study is to determine if Hyperbaric Oxygen (HBO) therapy improves salivary gland function in previously head-and-neck irradiated patients. The following will be evaluated: salivary a-amylase, IGF-1, Thrombospondin-1, and VEGF-A concentrations, resting and stimulated salivary flow rate and pH, and salivary buffering capacity. Demographic data, past medical/surgical histories, social history and habits, risk factors, medication list, nutritional status, stage and location of tumor treated, dose/duration of radiation, and time elapsed since radiation treatment will be reviewed and recorded. Subjects will complete a quality of life questionnaire, describe (presence/absence) dry mouth symptoms prior to HBO therapy, and provide current A1c level, or submit to a finger stick. The following groups will be evaluated: 1. Head-and-neck irradiated subjects with ORN (indicating HBO therapy) 2. Subjects with other conditions indicating HBO therapy (positive control), and 3. Head-and-neck irradiated subjects without ORN (negative control). Subjects will include 78 males or females, 18 years old and over. In total, participation will last 22 weeks.
The main objective of the study is the cure of osteoradionecrosis (ORN) at 12 months.
The purpose of this study is to determine whether hyperbaric oxygen therapy is effective in the treatment of osteoradionecrosis (late damage after radiotherapy) of the jaw.
There is currently not sufficient evidence that hyperbaric oxygen (HBO) benefits the surgical removal of necrotic bone in osteoradionecrosis patients. This study aims at testing the hypothesis that HBO does improve healing after surgical removal of necrotic bone in irradiated previous head and neck cancer patients compared to not receiving HBO.
1. Bisphosphonate-associated osteonecrosis of the jaw(ONJ)is detectable by positron emission tomography(PET). 2. Bisphosphonate-associated ONJ can be diagnosed and characteristically differentiated from other bony pathologies of the jaw(osteomyelitis, osteolytic lesions, and osteoradionecrosis)by PET imaging.
